STONE-MOLDING TOOL.

SPECIFICATION forming part of Letters Patent No. 787,546, datedApril 18, 1905. Application filed March 18, 1904. Serial No. 198,813.

To ctZZ whmn it may concern.-

Be it known that I, JAMES BERNARD WIL- soN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Stone-Molding Tools,

of which the following is a specification.

My invention conslsts of a stone-molding tool comprising a many-sided head formed of a plurality of polygonal plates of different widths, each side of said plates having a cutting edge and means for adjustably holding said plates, whereby the several sides of the head may present working faces of variable contours.

It further consists of novel features of construction, all as will be hereinafter fully set forth.

Figures 1 and 2 represent elevations at right angles to each other of a stone-molding tool embodying my invention, a portion of Fig. 1 being cut away to show the construction. Fig. 3 represents in perspectivea similiardtool, the form of the cutters being modi- Referring to Figs. 1 and 2 of the drawings, 1 designates a plurality of fiat plates or sheets of diflerent widths and in the present case of rectangular form, said plates being held on the bolt 2 and retained between suitable washers by means of nuts 3 on the ends of said bolts. It is evident that by arrangement of the plates any desired pattern may be produced on either face of the head, as at 4, 5, 6, 7, and 8, and that variable patterns may be formed on the several faces thereof.

In the operation of the tool one of the sides of the head is presented to the stone and worked thereover, whereby the contour of said side is imparted to the stone, thus molding the latter. Either of the other sides may be presented to the stone and worked, whereby a molding of a different contour may be produced.

In the form of device shown in Fig. 3 plates 9 are used, the faces of which are waved or sinuously curved, presenting increased cutting-surfaces, the contours of two cuttingfaces being plain and two being variable.

It is evident that sand, corundum, shot, or other abrasive substance may be placed on the stone, by which the action of the tool may be accelerated.

Various changes may be made in the details of construction shown without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

1. A stone -molding tool comprising a many-sided head formed of a plurality of polygonal plates of different widths, each side having a cutting edge and means for adjustably holding said plates, whereby every side of the head may be set'with variable contours.

2. A stone-molding tool comprising a head formed of a plurality of plates of polygonal form in combination with means thereon for securing said plates with their adjacent faces in contact and presenting a working face for every side of the head, each face being adapted to be set with variable contours.

3. A stone-molding tool comprising a head formed of a plurality of plates of polygonal form, each having an aperture therein, in combination with a bolt and means thereon for securing said plates with their adjacent faces in contact and presenting a working face on every side of said head at predetermined distances from said bolt.

4. A stone-molding tool comprising a head formed of a plurality of plates each having an aperture, in combination with a bolt adapted to enter the apertures of said plates for maintaining said plates with their adjacent faces in contact and presenting a working face on each'side of said head.
